Not exactly. 'Bel' is the only thing I've heard used to refer to an ancient being, an all-powerful one...much like YHWH exists now.
Centuries ago, the two of them fought. YHWH won, and Bel was shattered into shards, thrown into the demon world to become a multitude of different demons, all crowned with 'bel' in their name. If one of them were to kill all the others, and take their power, they would become King of Bel, ruler of all demons, and a being able to contest evenly with God. Following so far?
